How Seeking a Diagnosis in Adulthood Can Change Your Life. Philip Wylie sought a diagnosis of Asperger Syndrome at the age of 51 after reading an article about autism in an accountancy magazine and having a "Eureka" moment! This book discusses the process, the pros and cons, and the after-effects of receiving an autism diagnosis in adulthood. Outlining the likely stages of the journey to diagnosis, this book looks at what the individual may go through as they become aware of their Asperger characteristics and as they seek pre-assessment and diagnosis, as well as common reactions upon receiving a diagnosis - from depression and anger to relief and self-acceptance. Combining practical guidance with advice from personal experience and interviews and correspondence with specialists, the book discusses if, who to, and when to disclose, how to seek appropriate support services, and how to use the self-knowledge gained through diagnosis to live well in the future.
